IMPROVEMENT IN WELL-TUBES.

TO ALL WHOM IT MAY GONCERN:l y A Y Be it known that we, EDWIN A. PLATT, of Bristol, and GEORGE PLATT, of East Hartford, both in theeouuty of Hartford, 'and State of Connecticut, have invented certain nenr and useful Improvement in TubularWells; andto enable others skilled in the art to-male and use the same, We will proceed to describe its construction and operationrby referringto the dnawings, in whichthe same letters indicate like parts in each of the figures.

The nature of this invention will be understood from the specification and drawings.

The object desired to be attained thereby is to provide a free flow' of water, and,`at the same time, to prevent dirt from packing at the lowerend dt' the tube.

In the accompanying drawings- Figure 1 is aside view of a section ot tube;

Figure 2 is a sectional View of the same.

a is a section of a well-tube, which may be of any given size. One end, c, is pointed, or formed conical shape, for the purpose et' facilitating and directing its course While being driven into the`ground. This shape may be produced by securing a conical-shaped piece to the endof the pipe, or it may be produced by closing. up, Welding, and drawing down theihetal to a point. l

The upper end ot this section oi" pipe is provided with a screw-thread, cl, for the purpose of uniting one piece of pipe after another until driven to the desired depth, as in'the usual Way.

Thelovver section,ior.the pointed end. of this pipe, is perforated on all sides, for'some distance upward from the pointed end. The object of these holes is to allo'w a free flow of iiuid through from the outside to the inside of theA tube. l v

The inside of this tube, from the bottom to alittle distance abovethe perforations e, is provided With balls or pebbles, f, which are secured in place within the tube by means of au impedimenhsueh as, for example, the bars g, in such a 4way as to allow them to play up and down by the action of the pump or agitation of the'uid.

Thus the pipe may be driven to any desirable depth, good provision4 made for keeping in good `Working condition, and cheapand simple of construction. t Y

. We believe We' have thus shownthe nature, construction, and advantage of this invention so as .to enable others skilled in the art to make and use the same therefrom.

` `It is notin the slightest degree our object to filter `the water which passes through the openings e intothe pipe fi, but, on the other hand, it is the express object'of the pebbles f not to filter, but to keep the passage in close proximity with the perforations e open' and free for the passage of water, and, by the action of the pump 4and agitation of water, to eectually' prevent the clayey or earthy particles from becoming embedded at this point, (the lower end ofthe pipe.) We use coarse pebbles, andwthose only, and by the use of which we keep the pipe open, and secure a perfectly free passage of Water. u

We claim a well-tube, having lateral perforations and pebbles caged in the lower section, when so arranged that the pebbles shall be moved in their position by the action of the pump, all substantially as and for the lpurpose described.
